How to Process Workers' Comp Payments Through Payroll
7/27/2026
The processing question in workers' compensation reduces to one determination made repeatedly: which payment stream is this, and is it taxable?
Get that right and the mechanics follow. Get it wrong and you have either withheld tax on a non-taxable benefit — which the employee will notice — or failed to withhold on taxable wages, which produces a Form W-2 that will not reconcile and an under-deposit.

The general rule: payments made under a state workers' compensation act are not taxable; payments made by the employer as compensation generally are.
Our Workers' Comp Boot Camp and How Workers' Compensation Works cover the benefit structure.
Salary Continuation Is the Common Error
Many employers continue an injured employee's regular wages during the absence, either as policy or under a union agreement, and recover the statutory benefit from the carrier.
Those wage payments are taxable wages. Subject to federal income tax withholding, Social Security, Medicare, unemployment taxes, and reportable on Form W-2 — even though the underlying absence is work-related and the employer is reimbursed.
The reasoning: the payment is compensation from the employer, not a benefit under the workers' compensation act. The character follows the payer and the nature of the payment, not the reason for the absence.
The error to avoid: treating continued wages as non-taxable because "workers' comp isn't taxable." That produces under-withholding across the whole absence, a Form 941 that does not match the register, and a W-2 correction.
Where the employer receives the carrier's reimbursement, the mechanics vary — the reimbursement is generally an offset to the employer's wage expense rather than something that changes the employee's tax treatment. Coordinate with accounting so the employee's payroll records are not adjusted for what is an employer-side recovery.
Modified Duty Produces Two Streams at Once
The most operationally complex situation, and it is common.
An employee returning at reduced hours or reduced wages typically receives:
- Wages for hours actually worked — ordinary taxable wages, subject to full withholding
- A partial disability benefit from the carrier covering some of the wage loss — generally not taxable
- Possibly an employer supplement making up the remainder — generally taxable
Three payments, two tax treatments, one pay period. Payroll must process the wages normally, must not run the carrier's benefit through payroll as wages, and must treat any employer supplement as taxable compensation.
Two practical points:
Do not reduce the taxable wages by the benefit amount. The employee worked those hours and earned those wages; the benefit is a separate payment from a separate payer.
Watch the deduction capacity. Reduced wages may not cover the usual benefit deductions, creating an arrears situation that requires its own handling and authorization. See our voluntary deduction authorization guide.
See our return-to-work guide.
Benefit Deductions During Leave
The problem: benefit premiums remain owed, and there may be no wages to deduct from.
Where the absence runs concurrently with FMLA, the employer must maintain group health coverage on the same terms, which means arranging the employee's contribution through one of:
- Pre-payment before the leave begins
- Pay-as-you-go, with the employee remitting during the absence
- Catch-up, where the employer advances the premiums and recovers them from wages on return — under a written agreement made in advance
That last method fails when arranged retroactively. Recovering advanced premiums from returning wages is a payroll deduction requiring specific written authorization in most states, and an agreement reached after the fact is a weaker position than one documented before the leave.
Where salary continuation is being paid, deductions can generally continue normally, which is one practical advantage of that approach.
Other deduction considerations during leave: retirement plan deferrals generally stop where there are no wages, garnishments recalculate against whatever wages exist, and union dues follow the collective bargaining agreement.
See our cafeteria plans guide and FMLA/ADA/workers' comp guide.
Third-Party Checks
Where the carrier pays the employee directly, payroll's role is limited but not zero:
- Do not process the payment as wages. It is not employer compensation.
- Do record the absence for leave tracking, FMLA designation, and accrual purposes
- Do coordinate deductions, since the employee has no employer wages from which to deduct
- Do capture the data needed for premium reporting and for concurrent leave administration
- Do not issue a Form W-2 for the benefit
Where the employer is self-insured, the analysis is the same as to taxability — a benefit paid under the state act is not taxable regardless of who funds it — but the administrative arrangement differs and the payment may flow through the employer's systems, which creates a real risk of it being coded as wages by default. Configure a distinctly non-taxable payment type.
Year-End Treatment
Statutory benefits do not appear on Form W-2 at all — not in the wage boxes, not in Box 12, not in Box 14.
Salary continuation and supplements appear as ordinary wages in Boxes 1, 3, and 5, with the usual withholding.
A note on Box 14. Some employers use it to inform the employee of non-taxable benefits received. This is optional and unstandardized; if you do it, label it clearly as informational, because employees frequently misread Box 14 entries as taxable amounts.
Reconciliation. Confirm that no statutory benefit found its way into taxable wages, and that all salary continuation did. This is one of the recurring causes of a register-to-941 variance. See our year-end reconciliation guide.
Do not confuse this with third-party sick pay. Third-party sick pay — non-occupational disability paid by an insurer — has its own reporting regime, including a Form W-2 checkbox, potential Form 8922 filing, and a six-month FICA rule. Workers' compensation is different and simpler. See our third-party sick pay guide.
Premium Reporting Consequences
Payments processed through payroll may count as remuneration for workers' compensation premium even where they are excluded from other bases — and the definitions differ from taxable wages.
Salary continuation is generally remuneration. The carrier's statutory benefit generally is not. Confirm which payments your carrier includes, because reporting the wrong figure at the premium audit produces an assessment. See our premium calculation guide.
A Processing Checklist
- [ ] Identify which stream each payment belongs to before configuring anything
- [ ] Create a distinctly non-taxable payment type for any benefit flowing through your systems, including in self-insured arrangements
- [ ] Process salary continuation and supplements as ordinary taxable wages
- [ ] Process modified-duty hours as ordinary wages, without reducing them by the carrier's benefit
- [ ] Arrange benefit premium collection before the leave begins, in writing
- [ ] Designate concurrent FMLA and track the entitlement
- [ ] Confirm exempt employees' salary is not improperly docked
- [ ] Record the absence for accrual and leave purposes even where no payment runs through payroll
- [ ] Confirm the correct remuneration treatment for premium reporting
- [ ] Reconcile at year end that no statutory benefit entered taxable wages
- [ ] Keep workers' comp treatment separate from third-party sick pay reporting
Setting Up the Payment Types
The processing errors described above are nearly all prevented by configuration rather than by vigilance, and the configuration takes an afternoon.
Create distinct earnings codes rather than reusing existing ones:
- Salary continuation — workers' comp. Fully taxable, subject to all withholding, included in Form W-2 wages, and flagged as remuneration for premium reporting.
- Employer supplement — workers' comp. Same treatment.
- Modified duty wages. Ordinary wages, and where your state permits assigning modified-duty payroll to a lower-rated classification, coded so the allocation is reportable.
- Non-taxable benefit passthrough, for self-insured arrangements where the statutory benefit flows through your systems. Taxable to nothing, excluded from Form W-2, and excluded from premium remuneration.
Do not reuse the third-party sick pay codes. The reporting regimes differ entirely, and a shared code guarantees the wrong treatment somewhere.
Test each code before use. Run a calculation and confirm the resulting wage bases, the Form W-2 mapping, and the premium reporting flag. A code created by copying an existing one inherits whatever flags that code carried, which is the single most common source of a taxable-wage mapping error.
Document what each code is for, in a place the next person will find. Codes created for a specific situation and left undocumented are reused incorrectly within a year or two, and the person who understood the distinction has usually moved on.
Coordinating With the Carrier
Payroll cannot process these payments correctly without information that lives with the carrier or the third-party administrator, and the flow is rarely established deliberately.
What payroll needs, per claim:
- Whether indemnity benefits are being paid, from what date, and at what amount
- Whether the employer is receiving reimbursement for salary continuation, and on what basis
- The employee's work status — off entirely, modified duty, or released to full duty
- Current restrictions, where modified duty is in effect
- Any change in benefit status, promptly
What the carrier needs from payroll:
- Accurate wage information for benefit computation, which typically uses an average weekly wage over a defined lookback and includes elements payroll must identify correctly
- Confirmation of hours and earnings during any modified-duty period, since the partial benefit depends on actual wage loss
- Notice of termination, return to work, or any status change
Establish the channel deliberately. Name a contact on each side, agree the reporting cadence, and confirm how a status change reaches payroll within a pay cycle rather than after it. The common failure is a benefit that stopped or started weeks before payroll learned of it, producing an over- or under-payment that then requires correction.
Reconcile periodically. Compare the claims the carrier shows as active against the absences payroll is tracking. Discrepancies in either direction — a claim payroll does not know about, or an absence the carrier has closed — are worth resolving before year end rather than during it.
Frequently Asked Questions
Are workers' comp payments processed through payroll?
Statutory benefits paid by the carrier or state fund generally are not — they are not wages, are not taxable, and do not appear on Form W-2. What does run through payroll is employer salary continuation, employer supplements topping up a statutory benefit, and wages for hours actually worked on modified duty, all of which are ordinary taxable wages.
Is salary continuation during a workers' comp absence taxable?
Yes. Wages the employer continues during the absence are taxable compensation subject to federal income tax withholding, Social Security, Medicare, and unemployment taxes, and reportable on Form W-2 — even though the absence is work-related and even where the employer is reimbursed by the carrier. The character follows the payer and the nature of the payment, not the reason for the absence.
How do you handle pay for an employee on modified duty?
Three streams can occur in one pay period: wages for hours actually worked, which are ordinary taxable wages; a partial disability benefit from the carrier, which is generally not taxable and should not run through payroll as wages; and any employer supplement, which is taxable. Do not reduce the taxable wages by the benefit amount — the employee earned those wages, and the benefit is a separate payment from a separate payer.
How are benefit deductions handled when there are no wages?
Where FMLA runs concurrently, coverage must continue on the same terms, so the employee's contribution is arranged through pre-payment, pay-as-you-go remittance during the absence, or a catch-up recovery from returning wages under a written agreement made in advance. The catch-up method fails when arranged retroactively, since recovering advanced premiums is a deduction requiring specific authorization in most states.
Do workers' comp benefits appear on a W-2?
No. Statutory benefits paid under a state workers' compensation act appear nowhere on Form W-2 — not in the wage boxes, not in Box 12, not in Box 14, except where an employer voluntarily uses Box 14 for informational purposes, which should be labelled clearly since employees frequently misread Box 14 entries as taxable amounts.
Is workers' comp the same as third-party sick pay for reporting?
No, and conflating them causes errors. Third-party sick pay covers non-occupational disability paid by an insurer and has its own regime — a Form W-2 checkbox, potential Form 8922 filing, agent versus non-agent reporting allocation, and a six-month FICA rule. Workers' compensation covers occupational injury, is generally non-taxable, and is not reported on Form W-2 at all.
Going Deeper
Benefit structures, taxability of specific payment types, and remuneration definitions for premium purposes vary by state and by arrangement. Confirm the treatment of each payment stream with the carrier and, for self-insured arrangements, with tax advisors before configuring payment types.
